Impatiens plant named ‘Silt Salm09’

ABSTRACT

A new  Impatiens  plant named ‘Silt Salm09,’ particularly distinguished by the salmon-orange flower color, rose-like flower shape, medium green foliage, about medium growth vigor, and low mounded plant habit with good branching.

Latin name of the genus and species of the plant claimed: Impatienswalleriana.

Varietal denomination: ‘Silt Salm09’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Impatiens, botanically known asImpatiens walleriana, and hereinafter referred to by the variety name‘Silt Salm09’.

‘Silt Salm09’ is a product of a planned breeding program. The newcultivar ‘Silt Salm09’ has salmon-orange, double-type flowers, mediumgreen foliage, and a well branching plant habit.

‘Silt Salm09’ originated from a pollination made in July 2005 in acontrolled breeding program in Andijk, Netherlands. The parent was anunpatented hybrid seedling identified as ‘ID03-455-7’ with rose,single-type flowers. It was used as seed and pollen parent. In contrastto its parent, ‘Silt Salm09’ has a more orange hue of flower color,double-type flowers with more petals and somewhat deeper green foliage.

The seeds were sown in October 2005. ‘Silt Salm09’ was selected as oneflowering plant within the progeny of the stated cross in November 2005in a controlled environment in Andijk, Netherlands.

The first act of asexual reproduction of ‘Silt Salm09’ was accomplishedwhen vegetative cuttings were taken from the initial selection in thespring of 2006 in a controlled environment in Andijk, Netherlands.

Horticultural examination of plants grown from cuttings of the plantinitiated in the spring of 2006 in Andijk, Netherlands, and continuingthereafter, has demonstrated that the combination of characteristics asherein disclosed for ‘Silt Salm09’ are firmly fixed and are retainedthrough successive generations of asexual reproduction.

‘Silt Salm09’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length.

Plant Breeder's Rights for this cultivar were applied for in Canada onDec. 24, 2007 and in the European Union on Jul. 21, 2008. ‘Silt Salm09’has not been made publicly available more than one year prior to thefiling of this application.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawing shows typical flower and foliagecharacteristics of ‘Silt Salm09’ with colors being as true as possiblewith an illustration of this type. The photographic drawing, taken inlate May 2008, shows a 15 week old greenhouse grown plant of the newvariety.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Hillscheid, Germany, mainly in late May2008 on 14-15 week old plants that were growing on benches in agreenhouse. Culture of these plants had started around February 10 whenrooted cuttings were potted in 12 cm pots and grown at moderately warmtemperatures, between 15 and 20° C. in daytime.

BRIEF SUMMARY OF INVENTION

The following observations, measurements, and comparisons describeplants grown in a greenhouse in Hillscheid, Germany and in Andijk,Netherlands. The following traits have been repeatedly observed and aredetermined to be basic characteristics of the new variety. Thecombination of these characteristics distinguishes this Impatiens as anew and distinct variety.

-   -   1. Salmon-orange, double-type flowers.    -   2. Floriferous habit.    -   3. Medium green foliage, ovate to elliptical leaves.    -   4. About medium plant size.    -   5. Suitable as a bedding plant, for containers and as a        flowering pot plant indoors.

COMPARISON WITH COMMERCIAL CULTIVARS

‘Silt Salm09’ differs from ‘Silte Sal07,’ (unpatented) by a highernumber of branches, more floriferous habit, and smaller leaves.

‘Silt Salm09’ differs from ‘Didi Salmon Two,’ U.S. Plant Pat. No.15,908, by its slightly less pink hue of flower color, less dark greenfoliage, and by its generally more compact habit with shorterinternodes.
